2 Claims.

The present invention is concerned with meth- V An object of theinvention is to provide a method of application of such emblem which isespeciallyr effective, expeditious and convenient and does not requirethe exercise of any particular skill.

Another object is to provide a method of the above character by whichthe application of the emblem to an article with a lining, such forinstance as a lined handbag, is effected with inherent concealment ofthe clenched over prongs and without .penetration thereof through orinjury to the lining.

Another object is to provide a simple, rugged and inexpensive tool bywhich the method referred to may be effectively carried out.

This application is a .division Vof rmy copending application Serial No.331,565, filed April 25, 1940, and entitled Initial application andpatented on July 2, 1940, as Patent No. 2,206,806.

In the accompanying drawing in which is shown one of various possibleembodiments of the several features of the invention,

Fig. 1 is a .perspective view showing the initials appliedin place on .ahandbag,

Fig. 2 is a transverse sectional view on a greatly enlarged scale takenon the line 2-2 of Fig. 1,

Fig. 3 is a rear plan view of one of the initials used,

Fig. 4 is a transverse sectional view taken on line 4-4 of Fig. 3,

Fig. 5 is an edge view of the initial unit,

Fig. 6 is a detail sectional view on a larger scale taken on line 6 6 ofFig. 4,

Fig. 7 is a transverse sectional View showing the clenching tool withthe work in place, and

Fig. 8 is a View similar to Fig. 'I showing an intermediate stage in theclenching operation.

Referring now to the drawing, the bag I0 has mounted thereon one or moremetal initials L which may be conventional in external appearance. Eachinitial carries on the back thereof a staple S of soft bendable metal,preferably a strip of hard brass or, if desired, of soft steel. Thestaple is permanently affixed to the initial preferably by soldering thebase II thereto. The sides of the prongs I2 of the staple desirablyconverge at I3 to a point I4, and preferably the outer extremities ofthe prongs are turned outward slightly at I5. The junction between theprongs I2 and the base II are preferably not F.

sharply bent but extend in a rounded arc as at I6 on a substantialradius.

The individual staples are preferably produced by stamping with a dieand the die engages the metal sheet stock at the surface correspondingto the inner surface of the staple, so. that, as a consequence,theledges at the 'inner surface of the out turned points I4, are roundedoff as best shown at I1 in Fig. 6. The staples after being stamped outare desirably tumbled so that the surfaces thereof are rendered smooth,without burrs or sharp points, as best indicated in the drawing.Desirably the staple is so proportioned and positioned on the emblem,that the prongs thereof when flattened out substantially into the planeof the base, protrude slightly at their ends beyond `the respectiveedges of the emblem.

To apply to the handbag the initial or other emblem with the staplesoldered to the underface thereof, a clenching tool such as shown inFigs. 7 and 8 is preferably employed. This tool includes a base 20mounting a hardened metal anvil .2I with a smooth generally sphericallycurved convex surface 22. Thus the convex surface is devoid of anyretaining notches or depressions but is continuously curved on eachsection therethrough. Cooperating with the anvil is a hammer or plungerprovided with a shank 23 guided in a sleeve 24 and desirably urged to beretained in raised position by a coil spring 25 about the shank andreacting against the base of the handle knob 26, a rubber gasket 21taking the shock of spring return. The hammer presents a flat impactface 28, which desirably is covered with a piece of sole leather 28a,secured thereto inany suitable manner, whichv serves to protect theleather or other fabric 29 against which it is to be struck, frombecoming injured or indented by the impact and which also helps todampen the noise incurred by metal to metal` impact.

To apply the emblem to a handbag or similar article of leather 29 orother fabric, which is equipped with a lining 30, the emblem is placedin desired position upon the leather and with slight thumb pressure, thepoints I 4 are caused to penetrate the surface. The bag is laid upon theanvil 2| of the clenching tool, With the points of the staple superposedover the convex anvil face 22. Thereupon, the handle is struck one ormore blows, in which operation, as shown in Fig. 8, the points I4 of thestaple protrude under the leather and by reason of their rounded outturned points I4 in cooperation with the camming action of the convexanvil face, these points are caused to spread outward along the liningand without penetrating the latter. At the end of the hammer movement orusually upon one or more repetitions thereof 'with the bag displaced tobring the prongs successively to the center of the anvil, the staplewill have been completely clenched and the emblem will have been broughthome into intimate Contact wit-h the surface of the handbag. As.indicated in Fig. 2, the prongs in their nal spread position extendobliquely at 3| at their roots through the thickness of the leather, thelengths of the prongs extending in intimate contact with the back of theleather 4and alongthe lining and the outwardly turned points I4penetrate the leather slightly and may` clench it against the edge 32 ofthe initial L, which edge is slightly overlapped by the point of theprong and thereby enhances the security of attachment.

` By reason of thev curvature I6 at the roots of the prongs, the prongsflatten out in their clenched position as shown in Fig. 2,withoutinjuring the llining fabric as they frequently would, were theprongs to extend at a sharp angle relative to the base, in which casethe clenching operation might produce a rigid upstanding shoulder nearthe rootof the prong, which under the impact of the hammer might leavean unsightly Worn area'at the corresponding portion of the lining. Itwill be understood that while the curva- Vture I6 is-desirable for thereasons pointed out, it is within the scope of the invention as dened incertain of the claims, to use staples the prongs of which merge at asharp angle with the base.

Byreason of the conformation of the staples as set forth=and of theclenching tool, the staple thus reliably eiects a particularly secureand dependablehold of the emblem against the fabric, and in theclenching operation, the likelihood of other article between the anviland hammer, it will be understood that the particular construction ofclenching tool may be widely varied. The operating handle may, forinstance, have a hinged mount, to depress the plunger by a cammingaction.

While ordinarily a suiciently secure mount of the initial or otheremblem is effected with the use of but one staple for each unit, it willbe understood, that depending upon the character of the emblem (as forinstance for the initial W), more'than one staple could be used. Inspecial cases, if desired, special staples with three or more prongscould be used as will be readily -un derstood.

As many changes could be made in the above method and apparatus andmany` apparently widely different embodiments of this invention could bemade without departing from the scope of the claims, it is intended thatall matter contained in the above description or shown in theaccompanying drawing shall be interpreted as illustrative and not in alimiting sense.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is: Y l 1. The method of afxing a staplecarrying emblem unit to a structure of leather or the like, which methodconsists in superposing the emblem over the leather with the points ofthe staple slightly penetrating the leather,v pressing the the prongs oreither `of them penetrating the y lining, or injuring the lining in anyway is minimized.

In 'the application of the invention to articles that are not equippedwith linings as for instance to brief cases, the invention affordsfacilities for readily and reliably clenching over the prongs andindenting them into the leather, so that no sharp points or edgesprotrude that are apt to injure the fingers.

While the base of the clenching tool is bolted vtoa counter or table andprotrudes over the edge thereof, for facilityl of introducing the bag oremblem toward the leather against the reaction of a convex anvilstructure whereby the prongs of the staple will be cammed outward underthe leather, shifting the leather structure upon the anvil to bring theprongs successively over the top of the anvil, and striking each prongto cause .the same to dig into the leather.

2. The method of applying to an article of` fabric: an emblem having astaple which consists 'in preliminarily penetrating the outwardly turnedpoints of the staple into the fabric, supporting the fabric upon aconvex anvil, exerting downward pressure upon the emblem, thereby tocause prongs of the staple to be cammed outward under the fabric andthen shifting the fabric to center the prongs successively over theconvex anvil and striking each prong with the hammer to atten the sameout and cause the points to penetrate the fabric.
